2. Separate the power supply from the control board cable.
3. Screw the power supply into the standard 86-type wall box.
4. Connect the power board to the control board line, and align the buckle at 30 degrees to complete the installation.

App and Zigbee Gateway Connection

This is a Zigbee thermostat and requires a Zigbee gateway (hub) to connect to your home network and enable remote control via the app. The thermostat does not have a direct Wi-Fi module.

4. Add Thermostat:
   • Ensure your Zigbee gateway is powered on and connected to the app.
   • On the thermostat, when it is turned ON, press and hold the Up Arrow button for five seconds. The Wi-Fi icon (which indicates Zigbee network status) will flash on the thermostat display, indicating it has entered pairing mode.
   • In the Tuya Smart/Smart Life app, within your Zigbee gateway's interface, select "Add subdevice" or "Search device". The app will scan for nearby Zigbee devices.
   • Once the thermostat is found, add it to your gateway. You may be prompted to name the device.

Away Mode: When you are away from home, you can set the thermostat to Away Mode to maintain a lower, energy-saving temperature.

Anti-frost Function: This function protects your pipes from freezing by automatically activating heating if the temperature drops below a set threshold (e.g., 5°C).

Time Programming Instructions

You can set up to 6 periods for working days and 2 periods for holidays to automatically adjust the temperature according to your schedule. Refer to the detailed table in the included PDF manual for specific settings.

Maintenance

The Beok TGM50-ZB thermostat requires minimal maintenance. To clean the device, gently wipe the surface with a soft, dry, or slightly damp cloth. Do not use abrasive cleaners, solvents, or chemical sprays, as these can damage the thermostat's finish or internal components.

Troubleshooting

• Thermostat not powering on: Check the main power supply and ensure all wiring connections are secure according to the wiring diagram.
• No heating/cooling: Verify the thermostat is in the correct mode (Manual/Auto), the set temperature is above/below the current room temperature, and the heating/cooling system itself is operational.
• App connection issues: Ensure your Zigbee gateway is online and properly connected to the app. Check if the thermostat is in pairing mode (flashing Zigbee icon) when attempting to add it. Restarting the gateway or thermostat may help.
• Incorrect temperature readings: Check the "Sensor Selection" in advanced settings to ensure the correct sensor (internal/external) is chosen. You can also use the "Temperature Compensation" setting to calibrate the reading.
• "No Wi-Fi module!" error/confusion: This thermostat is a Zigbee device, not Wi-Fi. It requires a separate Zigbee gateway to connect to your home network and the app. It does not connect directly to Wi-Fi.
